Started learning to code mods today immediately ran into this problem below is a screenshot of my eclipse not sure what else to say any help is appreciated

The best recommendation is to Remove all mods, add them back one at a time, play for a bit; until you discover what’s crashing your game.  simply dumping a bunch of mods into your folder without knowing how they interact usually ends up like this.    You also need to look at your latest.log while the game is loading and spot any errors or incompatibilities that occur during load.   

ok updating java didnt fix it, played for like 10 minutes and the game crashed; ok i tried now uploading the debug.log here as attachment but its been half an hour now and it wont upload, is there another way for me to upload it or something?

I dont know how to fix this please help
